Question

我创建了一个twitter.Twitter对象，但无法将其存储到会话中。以下是我的代码。

t = twitter.Twitter(auth=twitter.OAuth(consumer_key, consumer_secret, 
    oauth_token, oauth_secret))    
request.session['t'] = t

但如果我存储像

这样的字符串

request.session['t'] = 't'

它有效，为什么？因为twitter #Twitter对象不是可序列化的对象？每次需要twitter #Twitter对象时，如何避免进行身份验证？以下是django追踪。

Answer 1

正如您猜测的那样，您只能存储pickleable个对象。

来自the docs

会话字典应该接受任何pickleable Python对象。有关详细信息，请参阅pickle模块。
